0be60963bd Fix some of the stuff in the PPC README file, and clean up legalization 
of the SELECT_CC, BR_CC, and BRTWOWAY_CC nodes.

5f0a3df176 Targets all now request ConstantFP to be legalized into TargetConstantFP. 
'fpimm' in .td files is now TargetConstantFP.

87c2c0e66b Implement Promote for VAARG, and allow it to be custom promoted for people 
who don't want the default behavior (Alpha).

d2c6fbef4a Remove TLI.LowerReturnTo, and just let targets custom lower ISD::RET for 
the same functionality.  This addresses another piece of bug 680.  Next,
on to fixing Alpha VAARG, which I broke last time.

c29fac7fce First part of bug 680: 
Remove TLI.LowerVA* and replace it with SDNodes that are lowered the same
way as everything else.

the scheduler will complain)

cff96008ac Add bswap, rotl, and rotr nodes 
Add dag combiner code to recognize rotl, rotr
Add ppc code to match rotl

Targets should add rotl/rotr patterns if they have them

7034571679 support functions that return bool (this "should" work but doesn't, 
*maybe* due to a legalizer bug.)

2ea271c8bf nasty paste-o, calls passing more than 8 arguments along were having 
args >8 put into the wrong place

e009e40008 this is a hack, which may or may not hang around. In short: 
whimper out of doing things the Right Way, and hack up a generic
'BRCALL' instruction, that gets generated when calls are lowered.
This gets selected by hand in the DAG isel, where it gets turned
into real (i.e. in tablegen) br.call instructions.

BUG: this dies on void calls, but seems to work otherwise?

b43dc0ff5b this should take care of calls to varadic functions, but it doesn.,t 
BUG: calling printf(string, float) will load the float into the wrong
register, completely forget about loading the string, etce

47cd4eeab0 I shoulda done this a *long* time ago (tm): implement calls properly, 
i.e. r1/r12/rp are saved/restored regardless of scheduling/luck

TODO: calls to external symbols, indirect (function descriptor) calls,
      performance (we're being paranoid right now)

BUG: the code for handling calls to vararg functions breaks if FP
args are passed (this will make printf() go haywire so a bunch of
tests will fail)

BUG: this seems to trigger some legalize nastiness

251185e626 DAG->DAG instruction selection for ia64! "hello world" works, not much else. 
use -enable-ia64-dag-isel to turn this on

TODO: delete lowering stuff from the pattern isel
    : get operations on predicate bits working
    : get other bits of pseudocode going
    : use sampo's mulh/mull-using divide-by-constant magic
    : *so* many patterns ("extr", "tbit" and "dep" will be fun :)
    : add FP
    : add a JIT!
    : get it working 100%

in short: this'll be happier in a couple of weeks, but it's here now so
the tester can make me feel guilty sooner.

OTHER: there are a couple of fixes to the pattern isel, in particular
making the linker happy with big blobs of fun like pypy.
